    Abstract

    Some steels fail to meet mechanical property requirements after oil quenching with subsequent tempering. If water is used in an attempt to facilitate better property formation, quenching cracks may then be encountered. To address these situations a methodology referred to as Alternately Timed Quenching (AT-Quenching) has been developed and is described in this paper. Computer simulation using water and air as the quenching media was used to develop AT-Quenching methodology. Based on the simulation results, the processing parameters of AT-Quenching were determined and then applied using a computer-controlled quenching tank. The results obtained from this study showed that the use of AT-Quenching could increase the depth of hardening without cracking.
